Class Hierarchy

• exceptions.Exception: Common base class for all exceptions.
  • zio.I2CNoAckError: Exception raised when an acknowledgement is not received, during an I2C transaction.
  • exceptions.StandardError: Base class for all standard Python exceptions.
    • exceptions.EnvironmentError: Base class for I/O related errors.
      • exceptions.IOError: I/O operation failed.
        • zio.ProtocolError: Exception raised when there are problems communicating with the agent.
          • zio.DisconnectError: Exception raised when the ZIO motherboard has been physcially disconnected from the host.
• object: The most base type
  • zio.GPIOChangeEvent: An event which indicates that the value driven on one of the input pins of a GPIO has changed.
  • zio.LockI
    • zio.Agent: Agent class is used to talk to agent program running in the ZIO board.
    • zio.GPIO: GPIO class is used to control devices over general purpose IO pins.
    • zio.PWM: PWM class is used to rapidly turn on and off an output pin.
    • zio.Sensor: Sensor class is used to access analog inputs usually driven by sensors.
  • zio.Module
    • zio.GPIO: GPIO class is used to control devices over general purpose IO pins.
    • zio.I2C: I2C class is used to access devices over the I2C bus.
    • zio.Motherboard: Motherboard class is used to perform operations that are global to all modules in the interface board.
    • zio.PWM: PWM class is used to rapidly turn on and off an output pin.
    • zio.SPI: SPI class is used to access devices over the SPI bus.
    • zio.Sensor: Sensor class is used to access analog inputs usually driven by sensors.
  • zio.SensorChangeEvent: An event which indicates that the value driven in one of the analog input pins has changed by atleast the tigger amount.
